These bits are made in Germany and are GUARANTEED TOUGH® - so tough that we are offering a NO BREAK GUARANTEE. If you have our bits, we have your back.

Milwaukee® 48-20-3918 4-Cutter Rotary Hammer Drill Bit, 5/8 in Drill Bit, 45/64 in SDS-Max Shank, 16 in D Cutting, Carbide Cutting Edge, 13 in OAL
The MILWAUKEE® MX4™ 4-Cutter SDS Max Rotary Hammer Drill Bits with solid head carbide deliver up to 5x longer life in concrete with rebar. Engineered with rebar guards to provide maximum durability in hard aggregate and rebar. Milwaukee designed their MX4™ 4-Cutter bits with sharp centering tips for exact spot drilling in concrete. The integrated 4-cutter design prevents lock-up in rebar, reducing downtime. Optimized flutes remove dust faster, reducing heat and delivering up to 15% more holes per battery charge. The wear mark indicator on each drill bit shows you when they no longer meet the ANSI requirement. These MILWAUKEE® MX4™ 4-Cutter Drill Bits are ideal for concrete with rebar and masonry applications.
